pip
allows easy installation of Python
packages that are hosted in Python Package Index
(PyPI
). While both Ubuntu
and Debian
provides installable Python
modules via apt
, it doesn't host as many modules and available version of the Python
modules are tied to the version of Ubuntu
or Debian
distribution.
You can get install latest version of most Python
modules by first installing pip
at the terminal using apt
.
